Pin your kid's way to a brilliant career as a scientist with these ideas

Sorry, Mom, those days are gone — at least if you want your kid to make it into an Ivy League college someday. These Pinterest science projects will show you how far we've come from the days of dioramas and volcano experiments, and perhaps serve as some fodder for future projects.

2. The eggshell geode

3. The bristlebots

Robotics are fascinating. Your kid will think so, too, after he or she builds a bristlebot. With some basic electronic supplies and toothbrushes, these mini-bots will start moving and shaking in no time.

4. The leak-proof bag

How does this work? It's the science of plastic polymers, ladies and gentlemen. This simple project shows how the molecules that comprise plastic materials can flex and stretch to create an effective and fascinating seal.

6. The jar beehive

Is your older child interested in going green? With some wood, plywood, jars and a beehive kit, this beehive project proves that it's possible to produce your own food sources in the comfort of your suburban backyard.

10. The aqua sand experiment

Even if a science fair isn't in your immediate future, this neat project demonstrates the brilliant chemistry of a simple water-repellent spray. (Not to mention it makes a pretty rad backdrop for any kind of underwater diorama your kid can imagine.)
